CA R D O O R SPECIFICATION forming' part 0f ALetters Patent N o.564,157', dated July 14, 1896.

Application filed November 11, 1895. Serial No. 568,646. (No model.)

To @ZZ whom, it may concern:

Be it known that I, JOHN W. PARKER, a citizen of the United States ofAmerica, and a resident of Atlanta, in the county of Fulton and State ofGeorgia, have made a certain new and useful Car-Door; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to figures of reference marked thereon, whichforni a part of this specification.

This invention relates to the class of cardoors in which t-he door mayeither form a complete closure or may form a ventilated closure for theopenings in the sides of the car, the object being to provide a superiorform of construction for a door of this class, whereby its life may beincreased and its usefulness improved, -the details of constructionwhereby these ends are attained being hereinafter fully set forth, andthe parts for which protection is desired fully set forth in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a portionof a car with this device in use as a ventilated door. Fig. 2 is avertical cross-section on the line 2 2, Fig. 1, further showing theconstruction of parts. Fig. 3 is a perspective view of one of thehangers of the perforated or screen door, and Fig. 4 is a like View ofone of the hangers of the outer or solid door. Fig. 5 is a sectionaldetail of the lock whereby the doors are held in their proper relativepositions regarding each other and the opening in the side of the car.

In the gures like reference-marks indicate corresponding parts in allthe views.

1 is the car, which may be of any class to which a door is applicableand which it is desired to lock.

2 is a bar) secured to each side of the car, above the correlativedoor-openings therein, and 3 is a track secured to the face thereof andusually consisting of a hat bar of metal screwed to said bar 2 in asuitable manner, with its upper edge projecting upwardly a suificientdistance above the upper side of the said bar for the ends of thehangers to strike should there be any tendency of the door-hangers tojump from said track.

4. and 5 are bars secured to the sides of the car, on either side of thedoor-opening, and forming jambs or stops for the sliding doors in theirmovements.

The door 6, which is the perforated one, so made by the use ofwire-cloth of standard mesh over the opening in said door, which shouldbe as large as possible, is in thickness say one-half as thick as thebar 2, and is seated against the face of the car so as to move acrossand cover thedoor-opening when in proper position. Hangers 7 and 8 actto suspend same from the track 3, rollers 9 in the upper ends of saidhangers serving to decrease the friction, and the ends 10 being extendeddownwardly a sufficient distance below the upper edge of said track andthe pe ripheries of said rollers to engage said track in case the doorshould be accidentally removed from its proper position.

The hanger 7, as shown partly in broken lines in Fig. 1, is in the formof a strap having an offset at 11 leading said strap out from the faceof the door G around theface of the track 3, whence it projects upwardlyand is turned backwardly and downwardly, the roller 9 thereof beingjournaled between the sides so formed, and the end projecting below theupper edge of the track, as hereinbefore stated.

The upper stile of the door G is extended beyond the edge of said doorand the strap of the hanger 8 has an eXtension12 lying along theprojected portion of the stile and being provided with an upturnedportion 13, which carries on its upper curved end a roller 9,

, and has an offset like the offset in the h. nger 7 at 11 for the samepurpose.

The strap of the hanger or the portion secured to the door may be of anyform, but the form shown is preferable, it being T- shaped, the verticalbar lying upon the side stile and the cross-bar lying upon the top stileand including the extension 12. The upright 13 of this hanger is thusprojected beyond the edge of the door, as is also the same portion ofone of the hangers vof the other door, for a purpose which will behereinafter shown.

IOO

14. is the solid or imperforate door, and is seated outside of the doorG, beingl suspended from the same track on hangers 15 and 1G. This doorshould be a little thicker than the door 6, and is seated with its upperedge partly (mostly) under the bar 2 and the track 3, the bevel 17 beingformed thereon -for the purpose of a water-shed, as seen in Fig. l.

The hanger 1G is formed like the hanger 7 and the hanger 15 like thehanger S, both h aving an oliiset portion 18 at .the angle of the bevel1.7, and the hanger 15 projects upwardly from the extended stile 19 ofthe door, like the upwardlyqiirejeeting portion of the hanger 8, eachhanger being in like manner provided with rollers O.

2O are brackets inside of the upper end of which the lower edge of thedoor 6 moves, and 21 a-re brackets which serve to hold the door 14 inplace when at its two limits of movement. These doors maybe locked inany of their positions by means of a device which I will now describe. Ahole is cut in the door 1-1, a like hole being eut in each edge of thedoor 6 and being provided with escutcheons 23, set at the points in saiddoor where they will register with the holes in the door 14 when thedoor 1i. is respectively over saiddoor G and ott of same, as seen inFig. 1, like holes a-nd escntchcons 2t being cut and placed on thesiding of the car under the escutcheons 23 when the door (l is in theposition shown in Fig. 1. A lever 25 is pivoted on an element 2G,screwed to the door 1l, over the hole therein, and an arm 27, curved ona radius from the pivotal point of said lever 25, is secured to saidlever in such a position that it will pass thron gh the said escutcheonand those marked 23 and 2t, thus locking the doors in any of theirpositions relatively to the doer-opening and to each other. For example,in Fig. 1 this arm 27 passes through the door 14, the escutcheon ...3 inthe door (i, and into the escutcheon 21 in the siding of the ear, thetwo latter-named escutcheons being the left-hand ones in said gure.lVhen the door 6 is pulled from over the opening in the side of the car,the arm 7 passes through the same escutcheons, except that theescutcheon (right) is moved under the door lt and the arm passes throughit. lVhen the door 1st is moved over the door 6, when said door 6 is inthe position shown in Fig. l, the escutcheon 24 (right) is substitutedfor the escutcheon 24, (left,) as is also the case with the escutcheontherewith.

Thc lever 25 is tachcd, and thus the doors be sealed in any position orarrangement.

In this device it will be observed that the screen-door may be movedover the opening in the side of the car without the door 1-1 aceompanying it, as would be necessary in order to form a perforated closure, and,indeed, this is the only time at which the wire-cloth and thescreen-door, 'both comparatively easily destroyed, are exposed totheelements and to having bales and barrels strike them. lVhen the door isopen, that is, the scrcendoor under the door 141, and both in theposition in which the latter is shown in Fig. 1, Y

the door 6 is under the door 14; and protected, and it is also protectedwhen the door 1 4 is over the opening, inasmuch as, owing to theengagement of the hangers 7 and 15 and 8 and 16, the said door 14:cannot be moved over the opening without carrying the door (5 with it.By reason of both doors being under the bar 2 it is obvious that so longas the lower edges of same are held nea-r the car the said doors may notbe thrown from their places, and by reason of the same fact and thewatern shed on the upper front edge of the door 1l no water may enterthe crack, whereby the cargo if it be near the door will not be wet pduringrain-storms and the interior of the car will at all times beperfectly dry.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent of the United States, is-

1. In a ear-door, a perforated door and an imperforate door mounted soas to move across the same, a track, and hangers, the hangers on oneside of each door interlocking' with the adjacent hanger of the otherdoor, tor the purpose specified.

2. In a door, two doors adapted to slide past each other their innerhangers interlocking, and their other .han gers being projected beyondthe ad jacent vertical edge oi' its door for the purpose specified.

3. In a car-door, two doors adapted to move across each other, holestherein registern g in sets, and a correlativo hole in the side oil. thecar, and a hasp pivoted to the outer door and carrying within the holethereof a pin adapted to enter each set of holes and engage said doors.

In testimony whereof I hereunto al'iix my signature in presence of twowitnesses.
